Newbie here... I’ve just ordered my first plug in hybrid and now looking at getting an EV charger installed. I’ve done a fair bit of research and am looking for some advice with regard to my options to locate the charger. As you can see from the photo below I have a large steel posted terrace that sits over the top of my car parking spaces. It seems from what I’ve read that you cannot have any other metal objects within 2.5 metres of the car or the charger? Is that correct? Obviously for me that would be impossible to achieve, so are there alternative earthing options available for me to still get a charger installed? It is quite probable that I could touch both the car (while it is charging) and one of the steel poles at the same time.
